PERFORMANCE FEATURES

SUBSONIC FILTER

The subsonic filter maximizes your Xtant amplifier’s output when a specifically tuned subwoofer system is used.

FULLY REGULATED PWM POWER SUPPLY

Xtant amplifiers feature a Fully Regulated, Pulse Width Modulated power supply. This power supply technology provides high efficiency and consistent output performance even when battery voltage is less than optimum.

CROSSOVER

This control allows the user to choose the exact low-pass frequency range the amplifier will play for the best possible performance.

BALANCED/FLOATING INPUT

When enabled, this circuitry helps to eliminate “system noise” associated with ground loops. When combined with the input sensitivity adjustment, it allows the amplifier to accept up to 17V of input signal.

PROTECTION CIRCUITRY

Both Thermal and Overcurrent protection are incorporated into Xtant amplifiers. In the event of a problem, the amplifier will reduce its power to maintain operation.

STATUS LEDS (LOCATED ON THE TOP OF THE AMPLIFIER)

Three LEDs indicate operational status of Xtant amplifiers. The red LED illuminates when the amplifier is “ON”, the yellow LED indicates that overcurrent protection is engaged, the orange LED indicates that the thermal protection circuit is engaged.

OPTIONAL PERFORMANCE ENHANCEMENTS

HIGH LEVEL ADAPTER (HLA)

High Level Adapters allow you to connect a source unit with speaker level outputs to your Xtant amplifier.

REMOTE LEVEL CONTROL (RLC)

The RLC or Remote Level Control allows a bass control to be adjusted remotely from the driver’s seat.

CONNECTIONS & CONTROLS

1. INPUT – Xtant3.1 and Xtant6.1 amplifiers feature RCA type input connections. Source units with an output signal level of 100mV–17V may be used.

2See "Balanced Input" for proper voltage level setting.

2.OUTPUT – These RCA type output connections send full range signals to additional amplifiers eliminating the need for "Y" connectors.

3.BALANCED INPUT – The balanced input switch serves two purposes. First, it helps eliminate noises being induced into the signal path by isolating the signal ground. Second, it is used to set the proper input voltage range:

OFF POSITION: 100mV – 8V

ON POSITION: 200mV – 17V

4.GAIN – This feature is used to fine-tune the input sensitivity of the amplifier to the source unit’s output level.

5.XOVER FREQUENCY CONTROL – This control allows the user to choose the exact low-pass frequency range the amplifier will play for the best possible performance. The upper end of the crossover frequencies can be selected from 40Hz–120Hz at 24dB per octave.

6.BASS BOOST – This feature will add up to 12dB of low frequency impact to the audio system. The Bass Boost is centered at 45Hz.

7.SUBSONIC – This feature limits the lower end of the low-pass frequencies sent to the subwoofers. The subsonic feature includes a selectable on/off switch, and a control knob used to adjust the lower end of the low-pass range. The subsonic setting can be selected from 20Hz-80Hz at 24dB per octave.

8.RLC – This port allows the use of the optional Xtant “remote level control” (RLC). The RLC is a bass control module that can be installed in any location within the vehicle for remote adjustments.

9.SPEAKER CONNECTION – Two sets of speaker terminals are provided for dual woofer applications. When connecting a single woofer, use only one set of speaker terminals.

WARNING: Xtant3.1 and Xtant6.1 amplifiers are not bridgeable.

10.POWER TERMINALS – This is the main power connection for the amplifier. The power and ground wire size should be the same gauge.

GND – The ground wire from this connection must be attached to bare metal on the vehicle.

REM – To turn the amplifier on/off, this terminal must be connected to the source unit’s "remote or electric antenna" wire.

+12V – The power wire from this connection must be attached to an inline fuse, then to the positive side of the vehicle battery.

WARNING: An outboard fuse must be installed in-line with the power wire within 18 inches of the battery.

SAFEGUARDS

WIRING REQUIREMENTS

Your Xtant power amplifier is designed for use with a 12 Volt, negative ground system. Installation of your Xtant amplifier in a vehicle with a POSITIVE ground system will result in severe damage to the amplifier, other audio components and/or the vehicle’s electrical components. If your vehicle uses a positive ground system, please consult your authorized Xtant retailer or specialty install shop.

Xtant3.1 and Xtant6.1 amplifiers have minimum wire gauge requirements for:

Power - 4 gauge Ground - 4 gauge Speaker cables - 12 gauge

FUSING REQUIREMENTS

Xtant3.1 and Xtant6.1 amplifiers are not fuse protected! A fuse must be installed in-line with the power wire at the battery, no further than 18" from battery. For safety, an outboard fuse should be added close to the amplifier. For fuse requirements for a single amplifier, refer to page 3 of this manual. In the case of a multi-amp system, use a fuse value equal to the combined value of all system amplifier’s power fuses.

LOCATION

A firm, flat surface with minimum vibration is ideal. Your Xtant amplifier may be mounted horizontally or vertically on a flat surface. The amplifier should NEVER be mounted upside

down. This ill-advised configuration can increase internal operating temperatures, decrease the amplifier’s ability to dissipate heat and speed up the amplifier’s automatic thermal shut down mechanism.

Under no circumstances should your amplifier be exposed to moisture and water.

To ensure adequate ventilation, the ideal location for your Xtant amplifier is an area away from any heat source, with at least 2 inches of clearance above and around the amplifier.

COMMON OVERSIGHTS

• The battery ground should remain DISCONNECTED at all stages of installation.

•Do not begin drilling until you have put your Xtant amplifier aside. Using the amplifier as a drilling guide may cause irreparable damage to the amplifier and void your warranty.

•Do not route any wires underneath or outside the vehicle body.

•Route signal wires (RCAs from source unit, speaker wires, etc.) away from power wires (power, ground, etc.) to avoid ground loops and other sources of noise.

INSTALLATION

Any deviation from the connection specifications recommended may cause serious damage to the amplifier, speakers and/or vehicle electrical system. Please double-check the connections before turning the system on.

PROCEDURE

1.Disconnect the vehicle’s negative battery connection.

2.Using the supplied allen wrenches, remove the four (4) screws from the annealed stainless steel amplifier cover. Put this aside until your installation is complete to prevent damage to the cover.

3.Place your Xtant amplifier at the predetermined mounting location. Using a felt pen, mark the exact position of the mounting holes on the mounting surface. Set your Xtant amplifier aside. Use a sharp, precise blade to cut small circles in the carpet and padding around the four marks denoting your mounting holes to expose the metal underneath. Use a center punch to make an indentation in the metal to ensure that you drill the exact position for the screws. Drill the four holes as marked.

4.Temporarily mount your Xtant amplifier using the four (4) long screws provided.

5.Run a power cable from the vehicle’s battery through the firewall and through the interior of the vehicle connecting one end to your Xtant amplifier’s B+ terminal and connecting the other end to the positive post on the battery.

NOTE: Install a circuit breaker/fuse within 18" of the battery. This effectively lowers the risk of severe damage to your vehicle should a short circuit ever occur in the audio system. Do not install the fuse in the fuse holder until all installation steps have been completed.

6.Find a good ground spot on the vehicle’s chassis and remove the paint to reveal bare metal at the contact point. Attach the ground wire to that contact point and connect the other end of the ground wire to the GND terminal of your Xtant amplifier.

7.Connect a Remote Turn-on wire from your source unit to your Xtant amplifier’s REM terminal (14 or 16 gauge wire). If your source unit does not have a dedicated Remote Turn-on lead, you may connect to the source unit’s Power Antenna lead.

8.Connect RCA cables from your source unit to your Xtant amplifier’s RCA input jacks. If RCA (low) level output is not available, use Xtant’s High Level Adapters (HLA—not included) to connect the speaker level (high level) wires to a set of RCA cables.

9.Connect your speakers to your Xtant amplifier’s speaker terminals using 12 gauge minimum speaker cable.

10.If you are using the RLC remote level control, mount the control in a convenient location in the driver’s area and route the wire and connect to your Xtant amplifier’s RLC port.

11.Double-check all the previous installation steps, in particular, the wiring and component connections. Securely mount the amplifier. Remove the protective film and screw the annealed stainless steel cover back onto the amplifier.

12.If everything is in order, reconnect the vehicle’s negative battery connection and begin adjusting your amplifier. NOTE: Be sure that the Gain Level on the amplifier is turned all the way down (counter clockwise) before proceeding with adjustments.

ADJUSTMENTS

CROSSOVER FREQUENCY SELECTION

Your Xtant amplifier has a built-in low-pass filter offering continuously adjustable crossover frequencies between 40-120Hz Hz. Adjust the setting according to your speaker component specification or to your particular preference—counter-clockwise for a lower frequency, clockwise for a higher frequency.

BALANCED INPUT ADJUSTMENT

OFF POSITION: when using Low Level (RCAs) without a Line Driver (100mV-7.5V)

ON POSITION: when using High Level (speaker) inputs with Xtant High

Level Adapters (HLA) or Low Level (RCAs) with a Line Driver (7.5V-17V)

GAIN CONTROL ADJUSTMENT

1.Turn the Gain control all the way down (counter-clockwise)

2.Set the volume control of the source unit to approximately 2⁄3 of its maximum output

3.Turn the balance control of the source unit to its center position

4.Leave the tone (bass/treble) controls at their usual position

5.Play a CD track with wide dynamic range

6.Use the Bass Boost Control to enhance the bass performance (if desired)

7.To locate the optimum input sensitivity setting, turn the Gain control clockwise until audible distortion starts to develop. Turn the sensitivity control counter-clockwise slightly to minimize the distortion.

8.If you often switch between sources (CD, tape, radio, etc.) you will need further adjustment since radio output level differs from that of CD or tape. In this case, you need to locate a balanced sensitivity setting which is best for the output level of your sources.

BASS BOOST CONTROL ADJUSTMENT

Select a boost level between 0dB and +12dB to enhance the bass performance for your sound system. Remember that every 3dB of boost costs you twice as much in power. Make sure to set the final gains after setting the Bass Boost to work best with your subwoofer/enclosure combination.

RLC PORT

If you are using the RLC control, make sure to take this into account during set-up procedures. Set-up the system with the RLC plugged in and with the level knob turned all the way up (clockwise). Adjust according to taste and to work best with your subwoofer system.

SUBSONIC FREQUENCY SELECTION

The subsonic filter maximizes your Xtant amplifier’s output when a specifically tuned subwoofer system is used. For example, if your subwoofer system is designed to play 40Hz-80Hz only, setting the Subsonic Filter to 40Hz will prevent the amplifier from wasting power trying to reproduce signals below 40Hz. The subsonic frequency settings are continuously adjustable from 20Hz-80Hz. Select the setting according to your preferred subwoofer system specification or to your particular preference.

OFF POSITION: defeats Subsonic Filter

ON POSITION: engages Subsonic Filter
